Last few issues, they even bashed CP/M in *every* editorial. Hard- and software articles about Z80/180/280 and CP/M weren't published for a long time, and (I guess) will never be again. But there are some CP/M groups here in germany being still active with hard- and software. For example, I just designed a Z280 single board (europe card) computer capable of running CP/M+ without externals (Power, floppy and terminal, of course). Fits onto ECB bus (64-pin VG connector), and contains 64/128K EPROM, 512K/1/2/4M DRAM, FDC, RTC, NVRAM, 2x RS-232. Clock speed 12.288 MHz, as soon as 12.5 MHz CPU is available. Meanwhile 9.8304 MHz. CPU runs with 16-Bit Z-BUS, the DRAM circuit supports 'Burst Mode'. The prototype board works very well, I'm now implementing my (180-proven) autoformat-BIOS for CP/M+ and re-layouting the PCB. Cost of the 'naked' PCB is supposed to be under $50. Tilmann Reh
